Lift propulsion and stabilizing system and procedure for vertical takeoff and landing aircraft that consists in applying simultaneously and combined as lifters during the initial portion of the climb and at the end of the descent of: a) some fans or electric turbines, EDF, and b) at least one rotor with external blades and/or rotary and/or c) the engine flow directed downwards and/or d) pressure air jets injected on leading edges control fins, and/or e) water jets and/or f) supplemented with aerodynamic lift produced during frontal advance of the aircraft, the stabilization is achieved by the gyroscopic stiffness of the rotor and two or more lifting fans oscillating fins and/or air jets located on two or stabilizers more peripheral points in a plane perpendicular to the vertical axis of the aircraft.

A grill having a platen with a plurality of heating zones. Each heating zone has a heating unit. Thermal transfer between adjacent heat zones is limited by air gaps and insulation. The heater unit of each zone has a heater that is disposed to attain substantially uniform temperature of the platen for that zone before a temperature sensor senses a set temperature during either pre-heat or recovery modes.

An apparatus and high speed process for heating and stretching a film having a bridle mechanism comprising a first heated roll and a second heated roll. The film is stretched as the film is transferred from the first heated roll to the second heated roll which rotates at a speed greater than the speed at which the first heated roll rotates. The film is fed into the bridle mechanism at a rate of about 1,500 fpm to about 2,500 fpm wherein it is stretched to a length that is up to about 450% greater than its initial, pre-stretched length. The increased contact between the large diameter heated rolls and the film and the short draw gap between the two heated rolls result in a highly stretched film having minimal neck-in.

An electric machine includes a housing defining an axis and having a coolant port disposed in an axial center of the housing, and a cylindrical stator surrounded by the housing and having a stator body in the form of a plurality of stacked laminations, with the stator having opposite axial ends terminating in winding heads. The housing and/or the stator is constructed to have cooling channels which extend in an axial direction and communicate with the coolant port to allow a flow of coolant from the coolant port via the cooling channels to the winding heads, or in opposite direction from the winding heads via the cooling channels to the cooling port.

A mattress is provided having three layers of differing properties stacked on top of each other which together have the effect of letting the user sleep in a simulated Zero G position without the aid of an articulating base. Two layers are contoured within the mattress let specific areas of the user's body sink further into the mattress than others. A cover with removable inserts is also provided for the mattress.

A thermostat includes a display and an illumination device that is configurable to illuminate the display in a partial illumination mode and a full illumination mode. In the partial illumination mode the illumination device generates a light intensity sufficient to review the settings of the thermostat without generating heat of a sufficient amount to disrupt thermostat measurements. The full illuminated condition is actuated upon interaction with the thermostat. Once interaction with the thermostat is completed the illumination device thermostat returns to the partially illuminated condition.

A method of calibrating an individual sensor whose output varies with at least one operating condition. A generic calibration curve is produced for the variation of the sensor reading with the at least one operating condition for the particular sensor type of the individual sensor. Calibration readings are then taken for the individual sensor at just a small number of discrete values for the at least one operating condition which fall within the full range of operating values for the at least one operating condition for which the sensor is to be calibrated. Using the calibration readings, the generic calibration curve is then scaled in order to fit the generic curve to the individual sensor.

The intermittent linear motor of this invention incorporates features which enhance the exhaust scavenging and cooling processes, as well as simplifying overall construction including a compression plenum below the piston where air displaced during a power stroke by the piston is immediately transferred through the combustion chamber allowing said compressed air to immediately begin scavenging exhaust gases as the piston is returned further displacing spent gases from the motor.

Novel suture removal instrument and technique are described herein. The invention utilizes a newly designed thermal filament to allow the tip of the suture removal instrument to be slipped under the stitch in order to heat and cut the stitch. Current suture removal techniques utilize scissors, forceps, and/or scalpels. These techniques, which are well known in the art, are problematic because they exert tension on the stitch and are associated with patient discomfort. Small stitches add to the difficulty of suture removal because they have less suture laxity for scissor insertion. The present invention therefore allows for more rapid suture removal with less patient discomfort and at a competitive or lower cost.

Problems such as thermal pole tip protrusion result from thermal mismatch between the alumina and pole material during the writing process. This, and similar problems due to inadequate heat dissipation, have been overcome by dividing the bottom shield into two pieces both of which sit on top of a non-magnetic heat sink. Heat generated by the coil during writing is transferred to the non-magnetic heat sink whence it gets transferred to the substrate. With this approach, the head not only benefits from less field disturbance due to the small shield but also improves heat dissipation from the additional heat sink

Disclosed is a secondary battery having improved safety against puncture and collapse. The secondary battery includes an electrode assembly including a first electrode, a second electrode, and a separator between the first electrode and the second electrode, a case receiving the electrode assembly, a cap plate coupled to the case, and a support plate electrically coupled to the first and second electrodes of the electrode assembly, the support plate being disposed between the electrode assembly and the case.

A lighting device comprises at least a light source (13, 33), a light emitting surface, an air inlet aperture (8, 9, 28), an air outlet aperture (8, 9, 28) and a cooling unit (4, 24) for moving air from the air inlet aperture (8, 9, 28) through the cooling unit (4, 24) to the air outlet. The air inlet aperture (8, 9, 28) and the air outlet aperture (8, 9, 28) are both located on the same side of the lighting device as at least part of the light emitting surface.

An optionally VOC-free silicone containing furniture polish is prepared using one or both of 1) a low viscosity silicone fluid and 2) a polydiorganosiloxane; and 3) a phosphonic acid dispersant together with water and one or more suitable surfactants.

A lighting apparatus is provided that includes a lighting harness having a harness power cord. Disposed internal to the harness power cord are pairs of electrical leads for providing electrical power to LED's. The harness power cord is plugged into a switch. There is also a power source cord having a first power cord source end that is plugged into the switch and the power source cord has a second power cord source end that is connected to a transformer. The transformer is capable of being plugged into a wall receptacle. The lighting harness is disposed internal to the skull of an animal such that the LED's are capable of illuminating the skull when supplied with electric power via the lighting harness.

In a heating device for conductive heating of a sheet metal blank with varying cross sectional surface, the sheet metal blank constitutes a direct component of an electric circuit, wherein an electrically conductive compensation element is provided which is placed onto a surface of the sheet metal blank, wherein a sum of the cross sectional surface of the sheet metal blank and the cross sectional surface of the compensation element results in a current conducting cross sectional surface.
